MultiMeter is an elegant AU/VST audio analyzer designed for audio engineers, producers, and musicians seeking precision. Developed with the JUCE framework, MultiMeter supports:

1. General Metering

• Employs a high-performance FIFO (First In, First Out) buffer to handle audio data between DSP and GUI threads.
• Features comboboxes and sliders to personalize metering behavior.

2. Level Meter

• Provides instantaneous visual feedback of audio signal levels with numeric value displays in decibels.
• Supports both Root Mean Squared (RMS) and peak readings.
• Enables user adjustment of the decay rate of meter ticks with multiple responsiveness options.
• Allows holding peak tick values for a specified duration to enhance the analysis of transient audio materials.

3. FFT Spectrogram Analyzer

• Presents a high-resolution Fast Fourier Transform (FFT) spectrum with logarithmically scaled frequency bins, displaying the frequency content over time with a curve of all frequency components in the incoming signal and enabling in-depth spectral balance analysis.
  Histogram

4. Histogram

• Visualizes the distribution of signal level dynamics over time.

5. Goniometer

• Converts L/R audio signals into Mid/Side representations that provide insights into the coherence of the stereo field distribution and phase differences between the left and right channels.

6. Correlation Meter

• Provides real-time readings of the phase correlation between left and right audio channels, ranging from +1 (fully in-phase) to 0 (wide stereo) to -1 (out-of-phase), for identifying phase issues and ensuring mono compatibility.
